The electrochemical determination of corrosion resistance of coated metals is more easy and simple compared to the salt fog test and atmosphere exposure and may provide more information.
涂层金属耐腐蚀性的电化学测定方法简便，快速，比盐雾试验和大气曝露等常规方法提供较多信息。

The surface topography and structure and morphology of the coating changed a little after 25 weeks salt fogexposure. As the result, the coating resistance hold high over the period of 25 weeks.
Polyurea coatings with different contents of hard segment polyaspartic ester(PAE) were investigated through aging tests of marine environment outdoor exposure and salt fog testing.
